How to resolve WCF CommunicationException was unhandled - wcf

Question

I have some problems.
the issue is CommunicationException error.
error message is
An error occurred while receiving the
HTTP response to
http://localhost:18080/WCFServices/TestService.
This could be due to the service
endpoint binding not using the HTTP
protocol. This could also be due to an
HTTP request context being aborted by
the server (possibly due to the
service shutting down). See server
logs for more details.
I wrote below source code.
TestServiceClient client = new TestServiceClient();
TestSettings[] voltages = client.GetTestSettings();
Error message appears above tilt word.
I want to synchronize Main Application and Client Application.
Above error is Client Application.
My app.config file is
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_ITestService" closeTimeout="00:01:00"

Without seeing your server side config it's going to be hard to help you troubleshoot.
Having said that, one of the things you can do to get the real underlying exception (you're not seeing what's really going on) is to configure WCF Tracing. Just drop that config snippet in the config file on your server side, and look through the logs generated. That should point you to the real problem. Make sure to take it back out when you're finished.
